Hi Anu

If you open the file in notepad, what separates the data fields ? Is it a
tab between the data, some symbol, or what ?

Best wishes Harald

Hi all,
i have a large data set ( which has around 400 columns and 200 rows).
this is the output of an instrument exported as a dat file. i am not
able able to open with excel (as it is too big). however i need only
selected columns(only 12 and they are always the same columns that are
needed) from the data set. can anyone tell me how i can get these
columns from the .dat files using VB6.
Thanks a lot in advance

Anu
